Exercise 20-part7

G. Component Diagram.

I learn the componet diagram from developer(2009).

G1. Scope of component diagram.

The different high-level reusable parts of a system are represented in a Component diagram. A component is one such constituent part of a system. In addition to representing the high-level parts, the Component diagram also captures the inter-relationships between these parts.

G2. Elements of component diagram.

• Component - The objects interacting with each other in the system. Depicted by a rectangle with the name of the object in it, preceded by a colon and underlined.(See figure 1.)
  

Figure 1. Componet symbol of componet diagram.

• Class/Interface/Object - Similar to the notations used in class and object diagrams.(See figure 2.)

Figure 2. Class/Interface/Object symbol of componet diagram.

• Relation/Association - Similar to the relation/association used in class diagrams. (See figure 3.)
